To ail whom it may concern Be it known that I, HARRY LIEBECK, a

citizen of the United States, and a resident of the city and county ofPhiladelphia, State of Pennsylvania, have invented an'Improvement inMachines for Making Toilet-Paper Rollsyofwhich the following is aspecification.

My invention has reference to machines for making toilet paper rolls,and consists of certain improvements which are fully set forth in thefollowing specification and shown in the accompanying drawings whichform a part thereof. l

The object of my invention is to provide a construction of paper windingmachine for making toilet paper packages in roll form which will permitof a practically continuous operation by bringing into winding positionone mandrel after another in rapid succession, with the result that theoutput of a single machine is greatly increased over what has heretoforebeen possible with this class of machine. I i

My invention consists in the combination of means for perforating, (withor without slitting a web of paper) with rewindlng means comprising anadjustable frame provided with two or, more detachable mandrels arrangedto be successively brought into operative winding position, and meansfor rotating the"mandrels when in operative winding position; further,in a machine of the character "stated, ,when provided with means forinsuring the rotation of the mandrels only when in winding position,whereby the operator may withdraw a filled mandrel when out of windingposition and after removing the paper rollsreadjust the man drel uponthe carriage and into operative relation with the means for rotating it;fur,-- ther, in providing the above described machine with perforatingcutters which so cooperate with the slitting cutters that the adjacentwebs, formed by the slitting cutters upon the single wide web, shall beperfo rated or cut, whereby the incisions shall be out of transversealinement and'the weakest portions of the'perforat ed webs will not allbe subjected to the windingtension at one time.

winding machine embodying my invention;

Fig: 2 is a plan view of the same with a portion broken away Fig. 3 is asectional elevation of the same on line 00-32 ofFig. 2; and Eggs. Land 5are sectional views of the means for rotating the mandrels,

2 is the main frameof the machine.

3 is the supporting shaft or mandrel upon which the large roll ofpaperis'placed; and said shaft 3 is provided with a brake wheel 4against which a friction shoe 5 mav be pressed under control ofthe screwshaft 6 extending to the front of the machine,

whereby a frictional resistance maybe put upon the large paper'roll tomaintain the paper web 7 under tension during the slitting, perforatingand rewinding operations. Any other suitable means may be employed forproviding this tension to the paper web.

The web of paper 7 passes under a-guide and feed roller 8, then upwardand over a drum v9 and thence tothe winding mandrel 35. While the paperis-p'assing about thedrum 9 it is first perforated transversely atintervals by the perforating blades 16 of a roller 10 and then'slitlongitudinally by the slitting cutters 12 on the shaft 17; The" drum 9is made with a series of circumferen-r tial cutting edges 15 forcooperating with the slitting cutters r12,'and is also provided with aseries *of transverse grooves 14 for cooperating with the perforatingcutting blades lG'for partly severing the web 7.

By the combined action of the cutters '12 and blades/16, a series ofnarrow webs of paper are formed, eachofwhich is perforated transverselyat intervals, so as to form short connected sheets which aresimultaneously wound'upon the mandrel 35. r

To prevent the pull of the mandrel rupturingthe perforated webs, Iprefer to arrange the blades 16 and the grooves 14: in suchmanner-thatthe adjacent transverse perforations, before slitting takes place, shallbe cut out of alinement or staggered, as, will be'understood byreference to Fig, 2. By this means there is considerable body of paperbetween the adjacent transverse perforations, and the f ictional Contactor, such paper with the drum feeds it forward and supports it'during theslitting operation, The feeding action of the roller 8 (which may be.covered with rubber) removes all excessive strain from the webs duringthe geared together by gearing 18 to insure their speeds being such asto properly cooperate in the manner above described. The drum 9 isdriven by a band wheel 19- having a disengaging clutch 52 of anysuitable construct-ion, which may be put into or out of action by ashifter shaft 20 having a pin 24 cooperating with a fixed cam surface25, said shaft 20 being rocked'by crank 21, link '22 and hand levermechanism 23. Any

other suitable means may be employed for putting the machine into andout of operation. A hand Wheel 19 may be employed on the shaft of thedrum 9 for adjusting the machine when the clutch 52 is out of gear.Thegeneral construction of the machine above described may be modifiedas to. its

elements and arranged to produce one or more webs to be rolled at onetime, but where there are a plurality of narrow webs to be made andwound, I consider it most important to arrange the perforating blades 16out of alinement.

I will now refer more particularly to the means for and manner ofwinding the perforated strips of paper upon a mandrel to form the rollsof paper in commercial form. 26. is-a pivoted frame which is pivoted at27 to the main fra e 2, and has, at its upper orfree end, a transverseshaft 29 journaled therein and provided'with disks 30 near each end.Between the disks 30 and removably supported, are the mandrels uponwhich the webs of paper are wound. One of the disks 30 is'provided witha series of shafts 36 having pinions 49 on one -end and chucks 37 on theotherend with which the end of the mandrel 35 engages and by which it isrotated. The mandrel 35 is provided with a pin 38, as shown in Fig. 4,and this pin engages a shoulder in the chuck 37 so that the rotation ofthe latter causes the mandrel to be rotated with it. The other end ofthe mandrel 35 is detachably supported upon a spring actuated center pin40, which'is carried in the other disk 30 and spring pressed toward themandrel-by means of a coil spring 41, as shown in Fig. 5. I have shownfour of the chucks 37 on one of the disks 30 and four of the 1 springactuated center pins 40 on the other disk 30, so that there .is capacityfor employing a plurality of mandrels between the two disks 30 at onetime. One Of'tl'le disks is provided with a series of notches 31corresponding in number to the spring actu-- ated center pins 40 andengaging these notches is a locking pin 33 carried by a .lever 32 whichis pi'votedto. the. frame 26.,

and held in locking position by means of a spring 34. By reference to Fig.. 3, itwill be se en that, by disengagingthe pin 33 from the notch 31the shaft 29, together with its disk 30 and mandrels, may be rotated soas to bring into operative position another mandrel to take the place ofthe one upon which the paper webs have been fully wound.

The operation of unlocking the shaft 29 and its disks and rotating it tobring anew mandrel into operative position 1r ay be ac complishedwithout interrupting the operation of the machine as a whole except fora moment; and. because of the facility 'of removing a filled mandrel'andbringing a fresh mandrel into operative position, the

capacity of themachine is greatly increased. lVhen the machine isinnormal operation, the pivoted frame 26 leans toward the drum 9 as inFig. 1; and when the mandrel is filled, the frame assumes a verticalposition as shown in Fig.3, at which time it becomes locked by means ofthe notch and locking lever 28. By raising this lever 28, the frame,together with its shaft 29, may be thrown, outward and away from thedrum 9 for permitting access thereto The rotation of the mandrel 35 181accomplished in the following manner chain wheel upon the drum 9 drivesa chain pulley 44 upon the shaft 27 by means of a chain (1r belt 43. Thepulley operates a second pulley 45 through a friction clutch 50, the

29 and its disks 30 are rotated into sue-- cessive positions ofadjustment and locked in said positions successively by the lockingmeans 32 and 33, the pinions 49 of the several chucks are successivelybrought into engagement with the rotating gear 48 which is journaled onthe pivoted frame 26 carrying the shaft 29. In-this way the chucks aresuccessively brought into operative po-' sition and rotated, forimparting rotation to their respective winding mandrels. From Fig. 1, itwill be seen that the chuck nearest to the drum9 will be'rotated bymeans of this power transmitting mechanism and consequently the mandrelconnected with the said chuck will be caused to rotate. During therotation of the mandrel, its speed will'be g'overnedbythe amount ofpaper to be wound which may pass to it from the drum 9, and a variationof thisspeed is permitted because of the presence of the frictionclutch50 between the two .chain orbelt wheels44 and 45.

Whenthe machineis' inoperation, 'the' tinually rest against the surfaceof the drum 9, as ndicated 1n Fig. 1, the saidaction being permitted byliftingi the lever 28 and moving the frame 26 and it's shaft29' towardthe said druni. As'fthewebs of paper are rolled upon the mandrel andincrease in diameter, they push the mandrel gradually away fronrthedrum; and when the proper size'of roll is co1npleted,-the frame 26 willhave been' lnoved from the position indicated in Fig, 1 to almostthe'position indi-'- cated in Fig. 3. .The operator then pulls the frame. 26into engagement with the lever 28 which locks to the transverse rod 53on the said frame. and'holdsthe same'stationany." He 'may then stop themachine by throwing the stop lever mechanism 23. Pre' vioushto thestopping of the machine he has inserted an additional mandrel betweenthe next chuck "and center pin to come into operative position. W'henthe parts have assumed the position indicated in Fig. 33nd the machineisstopped, the "operator disengages the {pin -33'-fr'on1 the notch 31androtates the shaft 29 with its disks and mandrels until the pin engagesthe next notch 31. The 'filled mandrel is then removed by disengaging;-it from the chuck and center pin and the paper webs broken and the'ends thus made quickly attached tothe new mandrel and, after disengagingthe lever 28:, the frame 26 with its shaft 29 is thrown into theposition indicated in Fig 1" and the lever device 23 agairi thrown toput the ma ,chine into operation. These operations are 'Trepeatedfwit-hthe'introduction of every new mandrel. Q 1 I It will be noted thatwhenthe disks 30' are rotated, the pinions'49 and ,the

tatd when in'winding position 'andwh'en the machine.is in ope'ratirm, sothat it is evident that-a new mandrel may be placed imposition and afilled .mandrel 1nay be removed while the machine is in operation,because the chucks carrying the last mentioned mandrels are not beingrotated.

-Ihave shown my inventionfladapted to :the slitting of wide webt7 into aseries of narrower webs, all of which are simultaneously wound upon the.same mandrel 35, but Iydo not restrict myself to such slitting, as therewindingfeatures of my invention may be applied to cases where onlyasingle web is operated upon;
